使用方法:	bash $0 [-n] [-f] [-u] [-F] [-P] [-D <Downloader>] [--path <PATH>] 
		bash $0 [-x] [--path <PATH>] [--url <URL>]

更新固件:
	-n			不保留配置更新固件 *
	-u			适用于定时更新 LUCI 的参数 *
	-f			跳过版本号、SHA256 校验,并强制刷写固件 (危险) *
	-F, --force-write	强制刷写固件 *
	-P, --proxy		优先开启镜像加速下载固件 *
	-D <Downloader>		使用指定的下载器 <wget-ssl | wget | curl | uclient-fetch> *
	--decompress		解压 img.gz 固件后再更新固件 *
	--skip-verify		跳过固件 SHA256 校验 (危险) *
	--path <PATH>		保存固件到提供的绝对路径 <PATH> *

更新脚本:
	-x			更新 AutoUpdate.sh 脚本
	-x --path <PATH>	更新 AutoUpdate.sh 脚本 (保存脚本到提供的绝对路径 <PATH>) *
	-x --url <URL>		更新 AutoUpdate.sh 脚本 (使用提供的地址 <URL> 更新脚本) *

其他参数:
	-B, --boot-mode <TYPE>		指定 x86 设备下载 <TYPE> 引导的固件 (e.g. UEFI Legacy)
	-C <Github URL>			更改 Github 地址为提供的 <Github URL>
	-H, --help			打印 AutoUpdate 帮助信息
	-L, --log < | del>		<打印 | 删除> AutoUpdate 历史运行日志
	    --log --path <PATH>		更改 AutoUpdate 运行日志路径为提供的绝对路径 <PATH>
	-O				打印云端可用固件名称
	-P <F | G>			使用 <FastGit | Ghproxy> 镜像加速 *
	--backup --path <PATH>		备份当前系统配置文件并移动到提供的绝对路径 <PATH> (可选)
	--check				检查 AutoUpdate 运行环境
	--clean				清理 AutoUpdate 缓存
	--fw-log < | [Cc]loud | *>	打印 <当前 | 云端 | 指定版本> 版本的固件更新日志
	--list				打印当前系统信息
	--var <VARIABLE>		打印用户指定的环境变量 <VARIABLE>
	--verbose			打印详细的下载信息 *
	-v < | [Cc]loud>		打印 <当前 | 云端> AutoUpdate.sh 版本
	-V < | [Cc]loud>		打印 <当前 | 云端> 固件版本

脚本、固件更新问题反馈请前往 ${Github}, 并附上 AutoUpdate 运行日志与系统信息 (见上方)
